流体

• The outermost layer of fluid clings to the walls of the tube, and its velocity is zero .
  最外层流体附着管壁，速度为零。
• In its hydrodynamic behavior, we can liken the dense phase to a liquid .
  从其流体动力学性状来看，可把密相看作近似乎液体。
• Amplifier self-oscillates at a frequency depending on the velocity of the fluid .
  放大器自激振荡的频率就取决于流体的速度。
• One of the astonishing properties of this superfluid is that it flows uphill .
  这种超流体的一个令人惊讶的性质是它向上流动。
• We continuously inject a tracer into a point in a steadily moving fluid .
  我们连续地将一种示踪物注入某稳定运动流体中之一点。
• Some of the quantities involved in elastohydrodynamic lubrication may be mentioned .
  下面提供一些与弹性流体动力润滑有关的量。
• It can maintain a fluid interface at a reference line in an inclined glass tube .
  它能保持流体分界面在倾斜的玻璃管中基准线上。
• Steady flow means that the way in which the fluid moves does not change with time .
  稳定流动的意思是说流体流动状态不随时间而变化。
• Let us summarize the governing equations for a fluid, previously deduced .
  现在让我们将上面推导出来的流体运动基本方程组归并在一起。
• When turbulence breaks out, a fluid behaves as though its viscosity has suddenly increased .
